๐ Wallet Wallet
A 'key holder' that lets you send and receive coins. It doesn't hold the coins themselves โ it holds the keys (permission) to move them.
๐ก
Common misconception โ does a wallet 'hold' your coins? No! Coins live on the blockchain; the wallet only keeps the โkeysโ to move them.
๐ฑ In plain terms โ the mailbox analogy
Your public address is like a mailbox address โ you share it so people can send you coins ๐ฌ. Your private key is the mailbox key ๐๏ธ โ only you have it, and you use it to take coins out (send). Sharing the address is fine, but if you share the key, anyone can take everything.
๐ง Types of wallets
| Type | Examples | Traits |
|---|---|---|
| ๐ฅ Hot wallet | MetaMask, exchange apps | Online & convenient, relatively less safe |
| ๐ง Cold wallet | Ledger, Trezor (hardware) | Offline & safest, less convenient |
| ๐ฆ Exchange wallet | Held on Upbit, Binance, etc. | Convenient, but not 'your keys' (the exchange holds them) |
๐๏ธ โNot your keys, not your coinsโ โ if you don't hold the key (private key) yourself, it's hard to call the coins truly yours.

โ FAQ
- Does a wallet hold my coins?
- No. Coins live on the blockchain; the wallet holds the private key (the key) that lets you move them.
- What happens if I lose my seed phrase?
- You may permanently lose access to your coins, since you can't restore the wallet. That's why you must back up the seed phrase safely and offline.
- Are coins on an exchange in my wallet?
- Technically the exchange holds them for you. You don't hold the private key yourself, so it's different from 'your wallet', with risk if the exchange fails.
